In my opinion, it is not Einstein's equation. It's Newton's equation applied to the speed of light. It's not v=0 but v=c. It just so happens that mc² is also the potential energy of a body at rest.
Yes, a photon's energy is all kinetic but so what? Newton's equation specified massive bodies.
Again, the 1/2 is BS but the winner of this debate is still to be determined.
- eesmith 5y agoA photon has no mass. Newton's equation specified massive bodies. Ergo, Newton's equation does not apply to photons. Einstein's equation does apply to photons. Ergo, Einstein's equation is not Newton's equation. For velocities much less than the speed of light, Einstein's equation is well approximated by Newton's equation.
